How I think about it is …
If the weather says “10% chance of rain”, what that means is in my city - there’s a 100% chance water will fall from the sky. But only 10% of us in the city will experience it.
- SkyPuncher 3y agoThat’s a really nice, practical way to think about it. After all, most people are trying to figure out how it will impact their plans. That type of positioning really puts it into perspective.
- DeRock 3y agoThat’s not exactly what it means, it’s a blended percentage of both the chance of any rain in an area multiplied by the coverage of that rain over the affected area. So a 50% chance it will rain somewhere, and if it rains it might rain in 50% of the area, would result in a 25% overall chance of rain.
